Description
Infectious diseases have been a major threat to survival throughout human history. Humans have developed a behavioral immune system to prevent infection by causing individuals to avoid people, food, and objects that could be contaminated. This current project investigates how ambient temperature affects the activation of this system. Because temperature is positively correlated with the prevalence of many deadly diseases, I predict that temperature moderates the behavioral immune system, such that a disease prime will have a stronger effect in a hot environment compared to a neutral environment and one's avoidant behaviors will be more extreme. Participants were placed in a hot room (M = 85F) or a neutral room (M = 77F) and shown a disease prime slide show or a neutral slide show. Disgust sensitivity and perceived vulnerability surveys were used to measure an increased perceived risk to disease. A taste test between a disgusting food item (gummy bugs) and a neutral food item (gummy animals) measured food avoidance. There was no significant avoidance of the gummy and no significant difference in ratings of disgust sensitivity or perceived vulnerability as a function of temperature conditions. There were no significant interactions between temperature and disease. The conclusion is that this study did not provide evidence that temperature moderates the effect of disease cues on behavior.

Description
Pro-environmental goals often pit immediate self-interest against future communal interest. Consequently, the motivation to behave in pro-environmental ways can be particularly difficult to maintain over time. By framing environmental ills as threats to one's chronic concerns, I suggest that chronic motivations, such as disease avoidance, can be leveraged to engender longer-lasting pro-environmental motivation. Specifically, I suggest that three distinct categories of environmental ills should be associated with distinct chronic concerns, and that the mechanisms that regulate these concerns should also regulate reactions to related environmental ills: pollution should engage a pathogenic disgust mechanism, wastefulness a moral disgust mechanism, and framing environmental outcomes as posing safety concerns should be linked to fear and anger mechanisms. Results of four experiments did not lend consistent support to the hypotheses. Neither situationally primed concerns nor motivation-relevant individual differences produced consistent results suggesting an association between the proposed motivations and the relevant environmental outcomes.

Description
Researchers have found inconsistent effects (negative or positive) of social relationships on self-control capacity. The variation of findings may depend on the aspects of social relationships. In this study, rather than examining overall social relationships and self-control, characteristics in social relationships were clearly defined, including social support, social connection and social conflict, to determine their specific effects on self-control. An online survey study was conducted, and 292 college students filled out the survey. For data analysis, path analysis was utilized to examined the direct effect and indirect effect from social relationships to self-control. Results showed social connection and social conflict may indirectly associate with self-control through stress, but social support does not. It may suggest, in traditional stress buffering model, it is the social connection in social support that really reduce the stress. Concerning the direct effects, social support and social connection were significantly associated with self-control directly, but social conflict does not. This result may support the Social Baseline Theory that positive social relationships have direct regulating effects. Results are good for guidance of experimental manipulation of social relationships in study of social influences of self-control.

Description
Traditional perspectives on sexual prejudice typically focus on the distinction between heterosexual ingroup and homosexual outgroup. In contrast, I focus on an affordance-management paradigm which views prejudices as resulting not from ingroup/outgroup relations, but instead from perceptions of the threats and opportunities posed by members of different groups. Past research has demonstrated that non-heterosexual target groups are perceived to pose a variety of threats, including threats to the socialization of young children, of child molestation, of disease, and to values. My research, however, suggests sexual prejudices arise for college students from beliefs that certain sexual orientation groups pose threats of unwanted sexual interest. For young adults, mating concerns are salient and should define relevant threats and opportunities--including those that might drive prejudices. For individuals with different active motivations, however, different threats and opportunities and threats are salient, and so the threats driving sexual prejudices may also differ. I extend my past research to consider how activating different fundamental goals (e.g., disease avoidance, parenting) alters patterns of sexual prejudice. I posit that activating disease concerns will increase prejudice specifically toward non-heterosexuals associated with disease (gay and bisexual me)--but not other non-heterosexuals (lesbians and bisexual women)--whereas activating offspring care will increase prejudice toward all non-heterosexual target groups, as all are perceived to pose socialization threats. To test this, heterosexual participants were randomly assigned to a parenting or disease-avoidance goal activation, or control condition, and then rated their general negativity towards heterosexual, bisexual, and homosexual male and female targets. They also rated their perceptions of the extent to which each target posed unwanted sexual interest, socialization, and disease threats. Contrary to predictions, activating parenting and disease avoidance systems failed to affect sexual prejudices. Furthermore, although the pattern of observed data was largely consistent with previously observed patterns, women's attitudes towards gay men in the control condition were more negative than that found in previous studies, as were men's attitudes towards bisexual and lesbian women. Multiple mechanisms underlie sexual prejudices, and research is needed to better understand the circumstances under which alternative mechanisms are engaged and have their effects.

Description
Men may engage in financially risky behaviors when seeking mates for several reasons: Risky behaviors can signal to potential mates one's genetic fitness, may facilitate success in status competition with other men, and may be a necessary strategy for gaining sufficient resources to offer potential mates. Once in a relationship, however, the same financial riskiness may be problematic for males, potentially suggesting to partners an interest in (extra-curricular) mate-seeking and placing in jeopardy existing resources available to the partner and the relationship. In the current research, we employed guided visualization scenarios to activate either a mating motivation or no motivation in single and in attached men and women. Participants indicated their preference for either guaranteed sums of money or chances of getting significantly more money accompanied by chances of getting nothing. As predicted, mating motivation led single men to become more risky and attached men to become less risky. These findings replicated across different samples and measures. Interestingly, in all three studies, women exhibited the opposite pattern: Mating motivation led single women to become less financially risky and attached women to become more risky. Thus, two additional experiments were conducted to explore the potential causes of this effect. The results of these latter experiments support the "mate-switching" hypothesis of risk-taking in attached women. That is, women who are able (i.e. have high mate value) were more risky in order to exit an undesirable relationship and move into a better one.

Description
People may conceptualize God as benevolent and as authoritarian. This research investigates the influence of these God-concepts on prosocial behavior; specifically whether such concepts differentially predict a set of beliefs about the self and the world, volunteer motivations, and intentions to volunteer for secular causes. Two studies, one correlation and one experimental, were conducted among college students who were Christians and indicated they believe that God exists. A measurement model of the concepts of Benevolent and Authoritarian God was first tested, and a conceptual path model was then analyzed. I found that concepts of a benevolent God were associated with a benevolent self-identity, perceived moral and religious obligations to help, and a high sense of personal responsibility with a total positive indirect effect on intentions to volunteer - mainly via internal motivations. In contrast, concepts of an authoritarian God were associated with a perceived religious obligation, having a positive indirect effect on intentions to volunteer via external motivations; but also with a low benevolent self-identity and low personal responsibility associated with amotivation (the disinclination to volunteer). Thus, there was a null total indirect effect of belief in an authoritarian God on intentions to volunteer. Future directions including the use of religious primes are discussed.

Description
Research on priming has shown that a stimulus can cause people to behave according to the stereotype held about the stimulus. Two experiments were conducted in which the effects of elderly priming were tested by use of a driving simulator. In both experiments, participants drove through a simulated world guided by either an elderly or a younger female voice. The voices told the participants where to make each of six turns. Both experiments yielded slower driving speeds in the elderly voice condition. The effect was universal regardless of implicit and explicit attitudes towards elderly people.

Description
Modern day driving continues to burgeon with attention detractors found inside and outside drivers' vehicles (e.g. cell phones, other road users, etc.). This study explores a regularly disregarded attention detractor experienced by drivers: self-regulation. Results suggest self-regulation and WMC has the potential to affect attentional control, producing maladaptive changes in driving performance in maximum speed, acceleration, and time headway.

Description
As the world's resources face increasing pressure from a growing population, it is critical that psychologists understand the motivational processes that lead to cooperation or defection in the context of social dilemmas. Research has uncovered several key strategies for encouraging maintenance of these resources, however, one area that remains understudied is the effect various emotions may have on cooperation. Furthermore, it is important to consider the specific type of desired behavior: reduction of consumption of a shared resource, or increased contribution to a shared resource. The current study takes a step in this direction, examining the effects of two self-conscious emotions, guilt and pride, on behavior in two different kinds of social dilemmas. Guilt, a prosocial emotion that has been described as a "behavioral interrupt mechanism," is predicted to increase cooperation in both a social trap game and a public goods dilemma game. However, its effects should be strongest in the social trap game, in which the desired behavior is reduced consumption. Pride, an emotion that is conceptually related to the constructs of status and power, is predicted to motivate action in both domains, by increasing both consumption in the social trap game and contribution in the public goods dilemma game. Results partially support these predictions: Whereas guilt and pride both had the predicted effects on consumption in the social trap game, neither had a significant effect on contribution in the public goods dilemma game. Individual differences are examined, as are the results of a Game Feedback Sheet, which yielded insight as to how participants understood the rules of the games, and why they chose the strategies they did. Results support the idea that emotions represent a potentially fruitful avenue of research in social dilemma cooperation, and possible future directions for this research are discussed.

Description
Beliefs about change reflect how we understand phenomena and what kind of predictions we make for the future. Cyclical beliefs about change state that events are in a constant flux, and change is inevitable. Linear beliefs about change state that events happen in a non-fluctuating pattern and change is not commonplace. Cultural differences in beliefs about change have been documented across various domains, but research has yet to investigate how these differences may affect health status predictions. The present study addresses this gap by inducing different beliefs about change in a European-American college sample. Health status predictions were measured in terms of predicted likelihood of exposure to the flu virus, of contraction of the flu, and of receiving a flu vaccine. Most differences were observed among those who have a recent history of suffering from the flu. Among them, cyclical thinkers tended to rate their likelihood for exposure and contraction to be higher than linear thinkers. However, linear thinkers indicated that they were more likely to receive a flu vaccine. The different patterns suggest the possibility that cyclical beliefs may activate concepts related to cautionary behaviors or pessimistic biases, while linear beliefs may activate concepts related to taking action and exercising control over the environment. Future studies should examine the interplay between beliefs about change and the nature of the predicted outcome.
